You can never accuse me of being one-sided. Although it may seem that I only pick on the medical and pharmaceutical industries, I actually enjoy picking on other “health” industries equally as much. Whether it be the “natural” products industry, psychotherapy, the weight loss industry, or bottled water, nobody is immune to my ridicule. I merely call it as I see it, and I love to point out the flaws in what’s being sold as “good health.” One industry in particular that I love to knock, simply because it’s so knockable, is the “anti-aging” shamsters.

So here’s the latest: I’m sure you’ve heard of DHEA (dehydroepiandrosterone). It’s a hormone produced naturally by the adrenal glands and is converted into other hormones, like testosterone and estrogen. It is sold as an over-the-counter supplement and touted heavily by anti-aging enthusiasts. Maybe you’ve been taking it yourself, to boost brain power, memory, and such. No? Oh, that’s good, because the first large scale study done to test supplemental DHEA’s effectiveness in brain function showed that it didn’t do diddly. That’s right…nothing, nada, nunca.

Here is the idea behind DHEA supplementation: DHEA is a natural steroid prohormone produced from cholesterol. It is the precursor of androstenedione (remember this stuff, baseball fans?), which can convert into the androgen testosterone and estrogens. DHEA levels peak during a person’s twenties, and then slowly declines with age. Because DHEA levels decline with age, and certain physiological functions also decline with age, while certain diseases increase with age (cardiovascular disease, Alzheimer’s, etc.), then the thought is that DHEA must be linked to age related health decline (oh, lord). So to prevent natural decline in physiological function, to decrease one’s risk of developing age-related illnesses, to improve one’s libido, energy levels, strength and bone density, and essentially to slow down or halt the aging process, one need only supplement with DHEA. Cha Ching! Or so the story goes.

But the latest research reported in the Journal of the American Geriatrics Society showed that supplementing with DHEA for as long as one year had no beneficial effects on brain function, memory or other cognitive abilities. According to lead researcher Dr. Donna Kritz-Silverstein, “healthy older adults should not turn to DHEA for the purpose of improving their cognitive function or overall well-being.” And I agree.

But here’s something older adults (and younger one’s too) can turn to quite confidently in their attempts to increase their natural levels of DHEA, and, in turn, age gracefully with increased strength, endurance, vibrancy and vigor: regular exercise, healthy diet, supplementation with basic vitamins and minerals, EFAs and a good antioxidant, regular bodywork, proper rest and recuperation, and minimizing toxin exposure (polluted air, polluted water, drugs, and so forth). And for boosting brain power, nothing…and I mean NOTHING…beats regular mental challenge like learning something new; and staying mentally engaged–reading, debating, writing, thinking, studying, problem-solving–at all times.

The research also showed that the subjects taking DHEA supplements had 2-3 times higher DHEA levels in the blood, so it’s not as if the body was just removing the supplemental form of the molecule (injecting the prohormone is, therefore, not a more effective alternative). Higher blood levels of DHEA had no benefit to mental function…zero. So I conclude by saying, once again, that things were designed the way they were for a reason. The body knows what to produce, at what concentrations, at any given time. It’s called Innate Intelligence, and every living thing has it. Man cannot improve on the wisdom of the body–not with Viagra, not with LASIK, not with pig-heart valves, nothing. And this latest research on DHEA is just another proof to that principle.

    This was really needed. I know that you twittered, Doh, when you posted a link, but I for one, need to have information from professionals like you, who post well-written scientific *facts* on issues. You clearly explain what DHEA can and cannot do and offer alternatives. How come so little attention is given to those?! Thank you, as always, for a great post!
